Answer:
7.irrational
8.integer ,whole number ,rational number
Step-by-step explanation:
7. that dash line on top of decimal shows that its keeps repeating
8. -18/6 = -3
3.5 hours each.... 7hrs if work/2 people = 3.5 hrs of work each
If you have a calculator, you can use the inverse cos " cos⁻¹ " key. Many upper level books write that as Arccos so as not to confuse you with a negative exponent. We do that because if you take the cosine of any angle, and then the inverse cosine of any angle, it leads you back to the original angle. Think of it as a big "UNDO" button.
To one decimal place, that result is 61.6 degrees.
Answer: Because the graphs of the two equations overlap each other
Step-by-step explanation:
Every point on the first line also satisfies the second equation.
This is the same as equivalent fractions
where 1/2 = 2/4 = 3/6 = 4/8
Graphing these on a number line would only show one dot.
